Family: Dicamptodontidae
Location: United States – Idaho and Montana
Size: 13 inches

The Idaho Giant Salamander is a fairly large terrestrial salamander found in the Rocky Mountains under rocks and logs. They are capable of climbing up vegetation as much as 8 feet.

Common Name: Plains Spadefoot Toad
Scientific Name: Spea bombifrons
Family: Scaphiopodidae
Locations: Canada, Mexico, United States
US Locations: Arizona, Colorado, Iowa, Kansas, Missouri, Montana, North Dakota, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, Utah, and Wyoming
Size: around 2.5 inches

The Plains Spadefoot Toad is a secretive toad. It spends most of its time underground only to come up to breed or to feed. They are also nocturnal so its even less likely that you will see them. The Plains Spadefoot Toad is a great burrower because of keratonized sheaths called spades on its rear feet. These help them dig easier. To escape freezing during winter, they even dig below the frost line to survive.

vulnerable
Common Name: Gold Striped Salamander
Scientific Name: Chioglossa lusitanica
Family: Salamandridae
Location: Spain and Portugal
Size: 6.5 inches or 164 mm

The Gold Striped Salamander is found in the northwestern part of the Iberian Peninsula. Mating takes place mainly during fall but the salamanders in the northwestern part of the range breed during spring. Females only lay up to 20 eggs at a time. The Golden Striped Salamander is terrestrial (lives on land) and nocturnal (active at night). The salamander has two cool superpowers. Their tongue can shoot out almost a third of an inch, allowing them to capture prey easier. They can also drop their tall if in trouble from a predator and the tail will still move minutes after. They can regrow a new tail too.

Common Name: Strawberry Poison Dart Frog
Scientific Name: Oophaga pumilio
Family: Dendrobatidae
Location: Costa Rica, Nicaragua, and Panama
Size: 1 inch

The Strawberry Poison Dart Frog is a colorful frog found in Central America. Because of its beautiful colors, the frog is often found in the pet trade. The bright colors of their skin is a sign to predators that they are toxic and should not be eaten. The Strawberry Poison Dart Frog accumulates its poison from its natural diet, so captive bred individuals are not poisonous. Females are also prefer to mate with brighter colored males. Both males and female Strawberry Poison Dart Frogs perform parental care. Males protect the egg clutches and keep them moist while the females carry the tadpoles after they hatch from the ground to water filled axils of bromeliads. The females also lay unfertilized eggs for the tadpoles to eat.

Common Name: Ensatina
Scientific Name: Ensatina eschscholtzii
Family: Plethodontidae
Location: United States, Canada, and Mexico
US Location: California, Oregon, and Washington
Size: 5 inches or 145 mm total length

The Ensatina Salamander is a complex of usually 7 different subspecies of salamanders found along the western coast of North America. They are referred to as a ring species or Rassenkreis, which is a series of connected populations that can interbreed with the close populations but can’t with the farther out populations.

The Ensatinas are terrestrial salamanders that are direct developing meaning their eggs hatch into small salamanders instead of tadpoles. Female salamanders usually lay around 10 to 15 eggs at a time on the ground. Breeding season in fall and spring but also happens during the winter too.

Common Name: Blue Legged Mantella, Expected Mantella, Tular Mantella
Scientific Name: Mantella expectata
Family: Mantellidae
Location: Madagascar
Size: 1 inch

The Blue Legged Mantella is found in the southern part of Madagascar in seasonal streams and wet canyons. The main threat to the frogs is the destruction of their habitat for grazing of cattle. Sapphire mining is also a threat in some areas. The Blue Legged Mantella is also found in the pet trade but people have had success breeding them in captivity.

Size: 4 inches

 

The Marbled Salamander is found throughout most of the eastern United States. They are mainly fossorial, spending most of their time underground. They do come to the surface during the fall to breed. They travel to breeding sites near depressions in the ground. The female lays their eggs under surface material. Eventually, the rain washes the eggs into the depression and it fills up with water. The female and male have different colors. The male’s stripes are white while the female’s are gray or silver.
